Frequently Asked Questions (FAQ)

Q: Can M30-6100646 be used as a direct replacement for M30-3100646?

A: Yes. Both parts share identical pitch (1.25mm), position count (6), connector type (header), mounting method (through hole), termination (solder), and electrical ratings (1A, 100V). The M30-6100646 is the active production equivalent.

Q: What are the differences between these two parts?

A: The M30-6100646 features an insulation height of 0.169" (4.30mm) compared to 0.165" (4.20mm) in the M30-3100646. The M30-6100646 uses brass contact material with specified finish thickness (80.0µin / 2.03µm) and includes mated stacking height specification (5.4mm). The M30-3100646 uses phosphor bronze contacts. Both maintain identical electrical performance and operating parameters.

Q: What is the packaging difference?

A: The M30-6100646 is supplied in tube packaging, while the M30-3100646 packaging is not specified. This difference does not affect functional compatibility or electrical performance.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and UL94 V-0 flammability rating. No compliance barriers exist for substitution.

Q: Why is the M30-3100646 listed as obsolete?

A: The M30-3100646 has been superseded by the M30-6100646 in the active product line. The M30-6100646 provides equivalent functionality with improved specifications and active manufacturing support.
