Engineering Selection Recommendations

The 1277360000 serves as the manufacturer-recommended substitute for the obsolete 1727630000. Both components maintain identical mechanical compatibility through matching pitch (4.60mm), connector configuration (20-position, 2-level), and mounting orientation (180° free-hanging).

The substitute part offers improved electrical performance with higher IEC voltage rating (320 V vs. 200 V) and increased IEC current capacity (13.4A vs. 10.3A). Extended operating temperature range (-50°C to 120°C vs. -50°C to 100°C) provides broader environmental applicability. Both parts maintain equivalent RoHS compliance and UL94 V-0 flammability certification.

Wire gauge compatibility differs slightly: the substitute accommodates 16-26 AWG (0.14-1.5mm²) compared to the original 16-28 AWG (0.2-1mm²). Applications utilizing 27-28 AWG wire require evaluation against the substitute's 26 AWG maximum specification.

Active product status of the 1277360000 ensures ongoing availability and supply chain continuity for new designs and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the 1277630000 directly replace the 1727630000 in existing installations?

A: Mechanical and electrical compatibility is established through identical pitch (4.60mm), position count (20), and mounting configuration (180° free-hanging). Wire gauge compatibility requires verification if applications use 27-28 AWG conductors, as the substitute supports maximum 26 AWG.

Q: What are the key differences between these two parts?

A: The substitute (1277360000) features enhanced electrical ratings (320 V IEC vs. 200 V, 13.4A IEC vs. 10.3A), extended temperature range (120°C vs. 100°C maximum), and active product status. Termination style differs: the original uses tension clamp technology while the substitute employs push-in spring termination.

Q: Are both parts RoHS and REACH compliant?

A: Both the 1727630000 and 1277360000 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the product status difference?

A: The 1727630000 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 1277360000 maintains active status, ensuring reliable supply for current and future applications.

Q: Does packaging differ between these parts?

A: The original part is listed with unspecified packaging, while the substitute is supplied in bulk packaging configuration.
