Key Parameters

Substitute Part Grouping Explanation

The 70430-140LF qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Connector Type and Style: Both are male blade power headers with identical connector geometry
• Position Count and Pitch: Both feature 10 positions at 0.236" (6.00mm) pitch with 5-row configuration
• Mounting and Termination: Both use through-hole mounting with press-fit termination
• Contact Specifications: Both employ gold-plated contacts at 30.0µin (0.76µm) thickness
• Flammability Rating: Both meet UL94 V-0 material flammability requirements
• Base Product Number: Both share the same base product number (70430), confirming design family alignment

The primary differences are product status (active vs. obsolete), RoHS compliance (compliant vs. non-compliant), and color specification (natural white vs. unspecified).

Parameter Comparison

Engineering Selection Recommendations

The 70430-140LF is the designated substitute for the obsolete 70430-140. Selection between these parts should be based on regulatory and compliance requirements:

For new designs or products requiring RoHS compliance: The 70430-140LF is the appropriate choice, as it meets RoHS compliance requirements while maintaining identical electrical and mechanical specifications.

For legacy system maintenance or non-RoHS applications: The 70430-140 remains functionally equivalent if inventory is available, though its obsolete status limits long-term procurement viability.

Both connectors maintain identical contact specifications, flammability ratings, and mechanical interfaces, ensuring direct PCB-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 70430-140LF be used as a direct replacement for the 70430-140 in existing designs?

A: Yes. The 70430-140LF maintains identical connector geometry, pitch, position count, mounting type, and contact specifications. PCB layouts and mating connector interfaces require no modification.

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This reflects the manufacturing process and material composition changes while preserving the connector's electrical and mechanical performance.

Q: Are there packaging differences between these parts?

A: The 70430-140 packaging is unspecified in available data. The 70430-140LF is supplied in tube packaging. Confirm packaging requirements with your procurement specification.

Q: Does the color difference (natural white vs. unspecified) affect electrical performance?

A: No. Color is a cosmetic specification and does not impact electrical characteristics, contact resistance, or mechanical function.

Q: What is the current rating for these connectors?

A: The 70430-140LF is rated for 3A per contact. Current rating data for the 70430-140 is not provided in available specifications.

Q: Are both connectors suitable for high-reliability applications?

A: Both connectors meet UL94 V-0 flammability requirements and feature gold-plated contacts with unlimited moisture sensitivity rating (MSL 1), supporting high-reliability applications. RoHS compliance status should be evaluated against your application requirements.
