Weidmüller 1696560000 Terminal Block Plug — Equivalent & Substitute Parts

Part Overview

The Weidmüller 1696560000 is a 21-position terminal block plug with female sockets, 0.197" (5.00mm) pitch, and 180° free-hanging wire entry configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

The part features screwless spring cage termination, tin-plated copper alloy contacts, and polybutylene terephthalate (PBT) housing with UL94 V-0 flammability rating. It supports wire gauges from 14–26 AWG (0.2–2.5 mm²) with a 7mm wire strip length and operates within IEC ratings of 17A at 400V and UL ratings of 10A at 300V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1696560000 is determined by the following critical parameters:

• Position count and pitch compatibility: All substitute parts maintain 21 positions with either 0.197" (5.00mm) or 0.200" (5.08mm) pitch
• Connector type and gender: All substitutes are plug-type connectors with female sockets
• Termination compatibility: Substitute parts use screw-based rising cage clamp termination, which differs from the original screwless spring cage design
• Wire entry orientation: Substitutes are available in 90° and 270° configurations, differing from the original 180° orientation
• Electrical ratings: Substitute parts support UL ratings of 15A at 300V, exceeding the original 10A specification
• Wire gauge support: All substitutes accommodate 12–26 AWG wire ranges, overlapping with the original 14–26 AWG range
• Housing material and flammability: Substitutes use polyphenylene oxide (PPO) housing with UL94 V-0 rating, compared to the original PBT housing

The Amphenol PCD ELFF series parts are active, RoHS-compliant alternatives with enhanced current ratings and improved moisture sensitivity levels (MSL 1 vs. Not Applicable).

Parameter Comparison

Engineering Selection Recommendations

Active Product Status: All Amphenol PCD ELFF series substitutes are active products with ongoing manufacturer support, addressing the obsolescence of the Weidmüller 1696560000.

Compliance and Certifications: All substitute parts maintain UL94 V-0 flammability ratings and are RoHS compliant, meeting modern regulatory requirements. The original part's compliance status for RoHS is not specified.

Electrical Performance: Substitute parts provide 15A UL current ratings, exceeding the original 10A specification. This enhanced capacity supports higher-load applications while maintaining 300V voltage compatibility.

Pitch Selection:

• ELFF21130 and ELFF21140 maintain the original 0.197" (5.00mm) pitch for direct mechanical compatibility with existing mating connectors
• ELFF21230 and ELFF21240 use 0.200" (5.08mm) pitch, requiring mating connector compatibility verification

Wire Entry Orientation:

• ELFF21130 and ELFF21230 provide 90° wire entry
• ELFF21140 and ELFF21240 provide 270° wire entry
• The original 180° orientation is not available in the substitute series; application layout must accommodate alternative orientations

Termination Transition: Substitutes employ screw-based rising cage clamp termination, replacing the original screwless spring cage design. This requires operator training adjustment but provides enhanced contact reliability and torque control (0.79 Nm / 7.0 Lb-In).

Housing Material Difference: Substitutes use polyphenylene oxide (PPO) instead of polybutylene terephthalate (PBT). Both materials maintain UL94 V-0 ratings; PPO offers improved thermal stability at 105°C operating temperature.

Frequently Asked Questions (FAQ)

Q: Can ELFF21130, ELFF21140, ELFF21230, and ELFF21240 directly replace the Weidmüller 1696560000?

A: Direct mechanical replacement depends on wire entry orientation and pitch requirements. ELFF21130 and ELFF21140 maintain the original 5.00mm pitch but use 90° and 270° wire entry instead of 180°. ELFF21230 and ELFF21240 use 5.08mm pitch, requiring mating connector compatibility verification. All substitutes use screw termination instead of screwless spring cage.

Q: What is the primary difference in termination style between the original and substitute parts?

A: The Weidmüller 1696560000 uses screwless spring cage tension clamp termination, while all Amphenol PCD ELFF substitutes use screw-based rising cage clamp termination with 0.79 Nm torque specification. Screw termination provides enhanced contact pressure control and reliability.

Q: Are the substitute parts RoHS compliant?

A: Yes, all Amphenol PCD ELFF series substitutes are RoHS compliant. The original Weidmüller part's RoHS status is not specified in available documentation.

Q: What wire gauge ranges do the substitute parts support?

A: All substitute parts support 12–26 AWG wire ranges, which encompasses and exceeds the original 14–26 AWG specification. This expanded range provides greater application flexibility.

Q: How do the electrical ratings compare?

A: Substitute parts provide 15A UL current rating at 300V, compared to the original 10A at 300V. This 50% increase in current capacity supports higher-load applications while maintaining voltage compatibility.

Q: What is the impact of the different insulation heights?

A: The original part has 0.500" (12.70mm) insulation height, while substitutes have 1.218" (30.94mm) insulation height. This dimensional difference affects board layout and connector spacing; mechanical fit verification is required.

Q: Which substitute part should I select for my application?

A: Selection depends on three factors: (1) required wire entry orientation (90°, 180°, or 270°), (2) mating connector pitch compatibility (5.00mm or 5.08mm), and (3) available board space for the increased insulation height. ELFF21130 and ELFF21140 are preferred for existing 5.00mm pitch systems; ELFF21230 and ELFF21240 require pitch compatibility confirmation.

Q: What is the moisture sensitivity level (MSL) of the substitute parts?

A: All Amphenol PCD ELFF substitutes have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The original part lists MSL as Not Applicable.
