Parameter Comparison

Engineering Selection Recommendations

Both the 10127720-201GLF and 0430452000 are active products with full RoHS compliance and UL94 V-0 flammability certification. The 10127720-201GLF maintains RoHS Compliant status, while the 0430452000 carries ROHS3 Compliant designation, indicating compliance with the most current RoHS directive requirements. Both connectors satisfy identical electrical specifications (600V rating) and thermal operating ranges (-40°C ~ 105°C). The primary material difference—copper alloy versus brass alloy contact material—does not affect electrical performance within the specified parameters. Insulation material composition differences (standard LCP versus glass-filled LCP) provide equivalent functional performance for the stated application envelope. Selection between these parts should be based on supply availability, lead time requirements, and established supplier relationships, as both meet all critical engineering specifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the 0430452000 be used as a direct replacement for the 10127720-201GLF?

A: Yes. Both connectors share identical pitch (0.118"), position count (20), row configuration (2 rows), mounting style (through-hole right-angle), shrouding (4-wall), termination method (solder), and fastening mechanism (locking ramp). Electrical ratings and operating temperature ranges are equivalent.

Q: What are the dimensional differences between these connectors?

A: Contact post length differs by 0.001" (0.02mm), and insulation height differs by 0.005" (0.12mm). These minor variations fall within typical PCB design tolerances and do not affect mating or functional compatibility.

Q: Are there material composition differences that affect performance?

A: Contact material differs (copper alloy versus brass alloy) and insulation material composition differs (standard LCP versus glass-filled LCP). Both material sets deliver equivalent electrical performance and meet identical flammability and compliance standards within the specified operating parameters.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant indicates adherence to the most current RoHS directive revision. Both designations confirm absence of restricted substances. ROHS3 Compliant represents the current regulatory standard.

Q: Are both connectors suitable for automotive, industrial, and medical applications?

A: The 0430452000 is specified for automotive, general purpose, industrial, medical, and telecommunications applications. The 10127720-201GLF does not list specific applications in the provided data. Both meet UL94 V-0 and voltage/temperature requirements applicable to these sectors.

Q: What is the current rating for these connectors?

A: The 10127720-201GLF current rating varies by wire gauge. The 0430452000 is rated for 8A. Verify wire gauge and current requirements against specific application needs.

Q: Are both connectors MSL 1 rated?

A: Yes. Both connectors carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control measures are required during storage or handling.
