Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents)

For applications requiring direct form-fit-function replacement with identical 2-side shrouding and 5.00mm pitch, the following active parts are recommended:

Weidmüller 1581540000 (Omnimate SL series) provides equivalent electrical performance with 15 A (UL) and 300 V (UL) ratings. This part features an extended operating temperature range of -50°C to 100°C and maintains UL94 V-0 compliance. The contact tail length of 0.126" (3.20mm) is slightly shorter than the original specification.

Phoenix Contact 1753877 (COMBICON MSTBV series) maintains 2-side shrouding and 5.00mm pitch with UL94 V-0 compliance. Current rating is 12 A (UL), which is lower than the original 15 A specification. This part is suitable for applications with reduced current requirements.

On-Shore Technology OSTOQ247050 (OSTOQ series) provides 2-side shrouding with 5.00mm pitch and 300 V (UL) voltage rating. Operating temperature range is -30°C to 105°C. Contact tail length is 0.157" (4.00mm), and insulation height is 0.157" (4.00mm), differing from the original specification.

Secondary Substitutes (Enhanced Shrouding)

For applications benefiting from increased mechanical protection through 4-side shrouding while maintaining 5.00mm pitch:

Weidmüller 1582000000 (Omnimate SL series) offers 4-side shrouding with 15 A (UL) and 300 V (UL) ratings. Operating temperature range extends to -50°C to 100°C with UL94 V-0 compliance.

Assmann WSW A-TB500-OQ24CV provides 4-side shrouding with enhanced current rating of 20 A (UL) and extended operating temperature of -40°C to 115°C. Contact tail length matches the original at 0.138" (3.50mm).

On-Shore Technology OSTOQ247150 (OSTOQ series) features 4-side shrouding with 5.00mm pitch and 300 V (UL) rating. Operating temperature range is -30°C to 105°C.

Tertiary Substitutes (Pitch Variant)

For applications where 5.08mm pitch is acceptable:

Assmann WSW A-TB508-OQ24CV provides 4-side shrouding with 20 A (UL) and 300 V (UL) ratings. Operating temperature extends to -40°C to 115°C. Pitch specification is 0.200" (5.08mm), representing a 0.08mm deviation from the original.

On-Shore Technology OSTOQ245350 (OSTOQ series) features 2-side shrouding with 5.08mm pitch and 300 V (UL) rating. Operating temperature range is -30°C to 105°C.

All substitute parts maintain RoHS compliance and tin contact mating finish. Selection should account for specific application requirements regarding shrouding configuration, current capacity, operating temperature range, and mechanical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1581540000 directly replace the TE Connectivity 2-282822-4?

A: The Weidmüller 1581540000 provides direct electrical and mechanical compatibility with identical 24-position count, 5.00mm pitch, 2-side shrouding, and 300 V (UL) voltage rating. Both parts feature UL94 V-0 compliance and tin contact mating finish. The contact tail length differs by 0.012" (0.30mm), which may require PCB layout verification. The part is active and RoHS compliant.

Q: What is the difference between 2-side and 4-side shrouded terminal blocks?

A: Shrouding configuration refers to the number of sides of the terminal block housing that provide mechanical protection. 2-side shrouded parts have protective walls on two opposing sides, while 4-side shrouded parts provide protection on all four sides. 4-side shrouding offers increased mechanical robustness and protection against accidental contact. Both configurations maintain identical electrical performance and pitch specifications.

Q: Are the On-Shore Technology OSTOQ parts compatible with the original TE Connectivity 2-282822-4?

A: On-Shore Technology OSTOQ247050 and OSTOQ247150 maintain 24-position count, 5.00mm pitch, and 300 V (UL) voltage rating. However, these parts feature significantly different mechanical dimensions: insulation height is 0.157" (4.00mm) compared to the original 0.472" (12.00mm), and contact tail length is 0.157" (4.00mm) versus 0.138" (3.50mm). These dimensional differences require PCB layout and connector interface verification before substitution.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: Pitch specification determines the center-to-center spacing between adjacent contact positions. The 0.08mm difference between 5.00mm and 5.08mm represents a 1.6% deviation. This difference may affect compatibility with mating connectors and PCB footprints designed for the original 5.00mm pitch. Assmann WSW A-TB508-OQ24CV and On-Shore Technology OSTOQ245350 with 5.08mm pitch require verification of mating connector compatibility before substitution.

Q: Which substitute part offers the highest current rating?

A: Assmann WSW A-TB500-OQ24CV and A-TB508-OQ24CV both provide 20 A (UL) current rating, which exceeds the original TE Connectivity 2-282822-4 specification of 15 A (UL). These parts are suitable for applications requiring higher current capacity while maintaining 300 V (UL) voltage rating and UL94 V-0 compliance.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are RoHS compliant. TE Connectivity 2-282822-4, Weidmüller 1581540000 and 1582000000, Phoenix Contact 1753877, and Assmann WSW A-TB500-OQ24CV and A-TB508-OQ24CV are ROHS3 compliant. On-Shore Technology OSTOQ247050, OSTOQ245350, and OSTOQ247150 are ROHS3 compliant. Compliance status is verified for all parts listed.

Q: What operating temperature range should be considered for substitute selection?

A: The original TE Connectivity 2-282822-4 operates from -40°C to 110°C. Weidmüller parts extend to -50°C to 100°C, Assmann WSW parts extend to -40°C to 115°C, and On-Shore Technology parts operate from -30°C to 105°C. Selection should account for specific application temperature requirements. Parts with narrower operating ranges may not be suitable for extreme temperature environments.

Q: Can the Phoenix Contact 1753877 be used as a direct replacement despite the lower current rating?

A: Phoenix Contact 1753877 provides 12 A (UL) current rating compared to the original 15 A (UL) specification. This part is suitable only for applications with maximum current requirements of 12 A or less. For applications requiring the full 15 A capacity, this part is not recommended. Verification of actual circuit current requirements is necessary before substitution.

Q: What are the mounting type differences between substitute parts?

A: The TE Connectivity 2-282822-4 and most substitute parts (Weidmüller 1581540000 and 1582000000, Phoenix Contact 1753877, Assmann WSW A-TB500-OQ24CV and A-TB508-OQ24CV) feature through-hole mounting for PCB insertion. On-Shore Technology OSTOQ247050, OSTOQ245350, and OSTOQ247150 specify solder mounting, which may indicate surface-mount or direct solder termination. PCB design and assembly process compatibility must be verified for these parts.
