Weidmüller 1503310000 Terminal Block Plug – Equivalent & Substitute Parts

Part Overview

The Weidmüller 1503310000 is a 17-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 180° wire entry orientation. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions. The part operates at IEC ratings of 17A/400V and UL ratings of 10A/300V, with screw-top clamp termination and free-hanging in-line mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Weidmüller 1503310000 are qualified based on the following critical parameters:

• 17-position configuration: All substitutes maintain identical position count
• Female socket type: All substitutes provide female socket connectivity
• Pitch compatibility: Substitutes operate at either 0.197" (5.00mm) or 0.200" (5.08mm) pitch
• Screw termination: All substitutes use screw-based clamp termination (rising cage clamp vs. top clamp)
• Free-hanging in-line mounting: All substitutes maintain identical mounting orientation
• Wire entry angle: Substitutes are available in 90°, 180°, and 270° configurations
• Electrical ratings: Substitutes rated at UL 15A/300V (exceeding original 10A/300V)
• Material compliance: All substitutes are RoHS compliant with UL94 V-0 flammability rating

The Amphenol PCD ELFF series substitutes provide active product status alternatives with enhanced operating temperature (105°C) and higher current capacity under UL standards.

Parameter Comparison

Engineering Selection Recommendations

For direct 180° wire entry replacement: ELFF17230 and ELFF17240 maintain the 0.200" (5.08mm) pitch specification of the original 1503310000. ELFF17230 provides 90° wire entry, while ELFF17240 provides 270° wire entry. Both are active products with enhanced UL current rating (15A vs. 10A) and specified operating temperature of 105°C.

For 90° wire entry applications: ELFF17130 operates at 0.197" (5.00mm) pitch with 90° wire entry. This represents a minor pitch deviation (0.03mm) and is suitable where mechanical space constraints favor this orientation.

For 270° wire entry applications: ELFF17140 operates at 0.197" (5.00mm) pitch with 270° wire entry, offering the same pitch deviation consideration as ELFF17130.

All Amphenol PCD ELFF series substitutes are active products with RoHS compliance and UL94 V-0 flammability certification, providing long-term supply continuity and regulatory compliance advantages over the obsolete Weidmüller original.

Frequently Asked Questions (FAQ)

Q: Can ELFF17230 or ELFF17240 directly replace the 1503310000 in existing designs?

A: ELFF17230 and ELFF17240 maintain identical 0.200" (5.08mm) pitch and 17-position configuration. The primary difference is wire entry angle (90° or 270° vs. 180°) and termination mechanism (rising cage clamp vs. top clamp). Mechanical fit and wire routing must be verified for your specific application.

Q: What is the pitch difference between 5.00mm and 5.08mm, and does it affect compatibility?

A: The difference is 0.08mm per position, totaling approximately 1.28mm across 17 positions. ELFF17130 and ELFF17140 operate at 5.00mm pitch. This minor deviation may affect mechanical alignment in tightly constrained connector housings. Verify mating connector specifications before substitution.

Q: Why do the Amphenol substitutes have higher UL current ratings (15A vs. 10A)?

A: The Amphenol ELFF series substitutes are rated at 15A under UL standards, exceeding the original 1503310000 rating of 10A. This represents enhanced electrical capacity and does not create compatibility issues; the substitutes can safely handle applications designed for the lower 10A rating.

Q: Are there differences in wire gauge compatibility?

A: The 1503310000 accepts 14-26 AWG (0.2-2.5mm²). All Amphenol ELFF substitutes accept 12 AWG, 14-26 AWG, providing expanded compatibility with larger gauge conductors. This is a superset of the original specification.

Q: What is the difference between TOP clamp and rising cage clamp termination?

A: The 1503310000 uses screw-top clamp termination. The Amphenol substitutes use rising cage clamp termination. Both are screw-based systems; the cage clamp mechanism differs in mechanical design. Torque specifications differ (0.4-0.5 Nm original vs. 0.79 Nm substitutes), requiring adjustment of assembly procedures.

Q: Does the housing material change affect performance?

A: The 1503310000 uses PBT (polybutylene terephthalate) glass-filled housing. Amphenol substitutes use PPO (polyphenylene oxide) housing. Both materials meet UL94 V-0 flammability requirements. PPO offers enhanced operating temperature specification (105°C vs. unspecified for original), providing thermal margin in high-temperature environments.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All Amphenol ELFF series substitutes are RoHS compliant and REACH unaffected, matching the compliance profile of the original 1503310000.
