Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-TB500-OP16 is determined by strict alignment of the following critical parameters:

• 16-position configuration with single-level layout
• 5.00mm (0.197") pitch spacing
• Vertical orientation with through-hole mounting
• Male pin, unshrouded header type
• Solder termination capability
• Contact tail length of 0.138" (4.60mm)
• Insulation height of 0.079" (2.00mm)
• UL94 V-0 flammability rating
• ROHS3 compliance status

The Phoenix Contact 1933325 satisfies all mandatory substitution criteria. This part maintains identical mechanical and electrical interface geometry, ensuring direct compatibility in applications designed for the A-TB500-OP16 footprint and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the A-TB500-OP16 and the Phoenix Contact 1933325 maintain active product status and full ROHS3 compliance. The substitute part 1933325 demonstrates equivalent or superior electrical performance characteristics, with UL current rating of 16 A compared to the primary part's 10 A specification, and IEC current rating of 12 A at 400 V. Both components carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity classification.

Selection between these parts should be based on availability, lead time requirements, and procurement cost considerations. The mechanical and electrical interface compatibility is assured through identical pitch, position count, mounting geometry, and termination specifications. No design modifications are required when substituting the 1933325 for the A-TB500-OP16 in applications operating within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1933325 be used as a direct replacement for the A-TB500-OP16?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing (5.00mm), position count (16), orientation (vertical), and termination method (solder through-hole). The contact tail length and insulation height are equivalent, ensuring PCB footprint compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity and electrical performance ratings. The 1933325 provides higher current capacity (16 A UL vs. 10 A UL) and includes IEC electrical specifications (12 A at 400 V). Both maintain identical UL94 V-0 flammability rating and ROHS3 compliance status.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. Current inventory shows 1066 units of the A-TB500-OP16 and 1670 units of the 1933325 available. Packaging format is identical, supporting equivalent handling and storage requirements.

Q: Do these parts require different PCB design considerations?

A: No. The identical pitch (5.00mm), contact tail length (4.60mm), and insulation height (2.00mm) ensure that PCB layouts designed for the A-TB500-OP16 require no modification to accommodate the 1933325 substitute.

Q: What compliance certifications apply to both parts?

A: Both the A-TB500-OP16 and 1933325 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry UL94 V-0 material flammability rating and MSL 1 moisture sensitivity classification.
