Substitute Part Grouping Explanation

Substitution for the Weidmüller 1727000000 is determined by the following critical parameters:

Number of Positions and Configuration: 10 positions total, 5 positions per level, 2 levels
Pitch: 0.200" (5.08mm) standard spacing
Header Type: Male pins with shrouded design
Mounting Method: Through-hole solder termination
Electrical Ratings: Minimum UL 300V compliance
Flammability: UL94 V-0 material rating
Orientation: Vertical mounting

Two substitute parts meet these core substitution criteria:

OSTVF105050 (On Shore Technology Inc.) - Direct functional equivalent with identical mechanical and electrical specifications for through-hole applications.

EDSTLZ976/5 (On Shore Technology Inc.) - Alternative with modified shroud configuration (4-side vs. 2-side) and different mounting approach (surface mount vs. through-hole), suitable only where PCB layout permits surface-mount termination.

Engineering Selection Recommendations

OSTVF105050 is the primary substitute for direct replacement applications. This part maintains identical mechanical footprint (5 positions per level, 2 levels), through-hole mounting configuration, and electrical compliance (UL 300V, 15A UL rating). The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Contact tail length and insulation height are within acceptable tolerance of the original specification.

EDSTLZ976/5 serves as an alternative only where design modifications are acceptable. The 4-side shroud configuration and surface-mount termination represent a different assembly approach. The configuration change from 5 positions per level to 10 positions per level alters the physical layout significantly. This substitute is suitable only for new designs or redesigns where PCB layout can accommodate the modified geometry and surface-mount process.

Both substitutes maintain UL94 V-0 flammability compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can OSTVF105050 be used as a direct drop-in replacement for 1727000000?

A: Yes. OSTVF105050 maintains the same 10-position configuration (5 per level, 2 levels), 0.200" pitch, vertical orientation, through-hole mounting, and UL 300V electrical rating. The contact tail length (0.154" vs. 0.177") and insulation height (0.866" vs. 0.872") are within acceptable mechanical tolerance for PCB mounting.

Q: What is the key difference between OSTVF105050 and EDSTLZ976/5?

A: OSTVF105050 maintains 2-side shrouding with 5 positions per level (matching the original), while EDSTLZ976/5 features 4-side shrouding with 10 positions per level. Additionally, OSTVF105050 uses through-hole mounting, whereas EDSTLZ976/5 uses surface-mount termination. These differences require PCB redesign if EDSTLZ976/5 is selected.

Q: Are there electrical rating differences between the substitutes?

A: Both substitutes meet UL 300V compliance. OSTVF105050 maintains the 15A UL current rating. EDSTLZ976/5 does not specify a current rating in the provided data. For applications requiring 15A capacity, OSTVF105050 is the appropriate selection.

Q: What is the operating temperature range for the substitute parts?

A: Both OSTVF105050 and EDSTLZ976/5 operate across -30°C to 105°C, which exceeds the original part's -20°C to 100°C range, providing improved thermal performance margin.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both substitutes maintain UL94 V-0 flammability rating, REACH unaffected status, and EAR99 ECCN classification, matching the regulatory profile of the original 1727000000.

Q: What is the inventory status of the substitute parts?

A: OSTVF105050 has 1003 pieces in stock. EDSTLZ976/5 has 857 pieces in stock. Both are classified as active products with ongoing availability.
