Weidmüller 1725900000 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Weidmüller 1725900000 is an 8-position terminal block header with male pins, shrouded on 2 sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 7A at 250V and UL ratings of 15A at 300V, with a temperature range of -20°C to 100°C. Substitute parts must maintain compatibility across pitch, position count, shrouding configuration, and electrical ratings to ensure reliable circuit board integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1725900000 is determined by the following critical parameters:

• Position Count & Configuration: 8 positions arranged as 4 positions per level across 2 levels
• Pitch Specification: 0.200" (5.08mm) nominal spacing between contact centers
• Header Type: Male pins with shrouding (2-side or 4-side acceptable)
• Mounting Method: Through-hole solder termination
• Electrical Ratings: Minimum UL 300V and 15A capacity
• Flammability Compliance: UL94 V-0 material rating
• Environmental Compliance: RoHS and REACH status alignment

The two substitute parts identified—EDSTLZ976/4 and OSTVF087150—both maintain the core 8-position, 4-per-level configuration and vertical orientation. However, each presents distinct trade-offs in pitch tolerance, shrouding design, and temperature operating range that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

EDSTLZ976/4 (On Shore Technology Inc.)

This substitute maintains exact pitch alignment (0.200" / 5.08mm) and identical position configuration. The 4-side shrouding provides enhanced mechanical protection compared to the original 2-side design. However, this part is specified for solder mounting only, whereas the original supports through-hole termination. This part is suitable for new designs or rework scenarios where solder-based assembly is the standard process. ROHS3 compliance and extended temperature range (-30°C to 105°C) exceed original specifications. Current rating is not specified in available documentation.

OSTVF087150 (On Shore Technology Inc.)

This substitute maintains through-hole mounting compatibility with the original design and supports the same 15A UL current rating. The pitch specification is 0.197" (5.00mm), representing a 0.08mm deviation from the nominal 5.08mm standard. This minor pitch tolerance may require PCB layout verification to confirm mechanical fit within existing footprints. The 4-side shrouding and extended temperature range (-30°C to 105°C) provide operational advantages. ROHS3 compliance and active product status ensure long-term availability. The green color differs from the original black housing.

Both substitutes carry UL94 V-0 flammability ratings, REACH unaffected status, and identical HTSUS classification, confirming regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can EDSTLZ976/4 be used as a direct replacement for 1725900000 in existing through-hole PCB designs?

A: No. EDSTLZ976/4 is specified for solder mounting only and does not support through-hole termination. PCB redesign and assembly process modification would be required. Use OSTVF087150 for through-hole compatibility.

Q: What is the significance of the 0.197" (5.00mm) pitch on OSTVF087150 versus the 0.200" (5.08mm) specification?

A: The 0.03mm per-position cumulative tolerance across 4 positions per level results in approximately 0.12mm total deviation. Existing PCB footprints designed for 5.08mm pitch must be verified for mechanical clearance. Contact pad spacing and via placement should be reviewed before implementation.

Q: Are both substitute parts suitable for applications requiring -20°C to 100°C operation?

A: Yes. Both EDSTLZ976/4 and OSTVF087150 support extended temperature ranges (-30°C to 105°C), which encompass the original -20°C to 100°C specification. No thermal derating is required for the original operating window.

Q: What is the difference between 2-side and 4-side shrouding?

A: 2-side shrouding (original) provides mechanical protection on two opposing sides. 4-side shrouding (both substitutes) provides protection on all four sides, reducing cross-talk and improving mechanical robustness. 4-side shrouding is generally preferred for high-density applications but may affect PCB layout spacing.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. Both EDSTLZ976/4 and OSTVF087150 are ROHS3 compliant, exceeding the original RoHS compliance status. Both are REACH unaffected, matching the original regulatory profile.

Q: Which substitute is recommended for new product designs?

A: Selection depends on assembly methodology. For solder-based assembly, EDSTLZ976/4 is appropriate. For through-hole assembly, OSTVF087150 is appropriate. Both are active products with confirmed long-term availability.
