Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1688000000 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Plug with female sockets, 14-position, 0.138" (4.60mm) pitch
• Electrical Ratings: 17A (IEC) / 10A (UL) current capacity; 320V (IEC) / 300V (UL) voltage rating
• Termination Method: Screw-clamping yoke (tension sleeve) termination
• Mechanical Interface: 180° free hanging (in-line) mounting; M2 screw size
• Wire Compatibility: 14-28 AWG / 0.2-1.5mm² wire gauge range
• Environmental & Compliance: UL94 V-0 flammability rating, IP20 ingress protection, RoHS compliance, operating temperature -50°C to 100°C

The substitute part 1687770000 maintains full electrical and mechanical equivalence across all specified parameters, with the exception of housing color (orange vs. black) and product status (active vs. obsolete). Color variation does not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1687770000 is a direct functional equivalent to the obsolete 1688000000 terminal block plug. Both components are manufactured by Weidmüller within the Omnimate BL series and maintain identical electrical ratings, mechanical specifications, and compliance certifications.

Primary Advantage of 1687770000: Active product status ensures ongoing availability, supply chain continuity, and manufacturer support. The part is RoHS compliant and carries identical UL94 V-0 flammability certification and REACH unaffected status.

Non-functional Difference: Housing color differs (orange vs. black). This variation does not affect electrical performance, mechanical compatibility, or environmental ratings. Color selection may be determined by application-specific identification or wiring convention requirements.

Compliance Equivalence: Both parts maintain identical certifications across IEC and UL standards, with matching current and voltage ratings (17A/320V IEC; 10A/300V UL). Screw torque specifications, wire gauge compatibility, and operating temperature ranges are identical.

For applications requiring the 1688000000, the 1687770000 provides full functional substitution with the added benefit of active product status and bulk packaging availability.

Frequently Asked Questions (FAQ)

Q: Can the 1687770000 directly replace the 1688000000 in existing installations?

A: Yes. The 1687770000 is electrically and mechanically equivalent across all specified parameters. Both components feature identical 14-position, 4.60mm pitch configuration, 17A (IEC) / 10A (UL) ratings, screw-clamping termination, and 180° free hanging mounting. The only difference is housing color (orange vs. black), which does not affect functional compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: UL94 V-0 flammability rating, RoHS compliance, REACH unaffected status, and equivalent IEC/UL electrical ratings. Moisture sensitivity level (MSL 1 - Unlimited) and ingress protection (IP20) are identical.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 1688000000 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 1687770000 maintains active product status, ensuring ongoing supply, manufacturer support, and availability in bulk packaging. For new designs or replacement applications, the active substitute is recommended.

Q: Does the color difference (black vs. orange) affect wire gauge or termination compatibility?

A: No. Color is a cosmetic variation only. Both parts accept identical wire gauge ranges (14-28 AWG / 0.2-1.5mm²), use M2 screw termination with identical torque specifications (0.2-0.25 Nm), and feature 6mm wire strip length. Electrical and mechanical interfaces are fully compatible.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 1688000000 and 1687770000 operate across the identical temperature range of -50°C to 100°C with no derating or performance variation.

Q: What packaging options are available for the substitute part?

A: The 1687770000 is available in bulk packaging, providing flexibility for production and inventory management. The original 1688000000 packaging specification was not defined in the product data.
