Parameter Comparison

Engineering Selection Recommendations

The M80-7530445 is the manufacturer-recommended substitute for the obsolete M80-6170445. Selection of the M80-7530445 is supported by the following factors:

Product Status: The M80-7530445 maintains active production status, ensuring long-term component availability and supply chain continuity compared to the obsolete M80-6170445.

Compliance Certifications: The M80-7530445 achieves ROHS3 compliance, addressing regulatory requirements for new designs and manufacturing processes. The M80-6170445 is RoHS non-compliant, limiting its use in applications subject to RoHS directives.

Electrical Performance: The M80-7530445 provides enhanced voltage rating of 800V compared to 120V in the M80-6170445, offering greater electrical margin in applications requiring higher voltage tolerance. Current rating remains equivalent at 2.2A per contact.

Material Composition: The M80-7530445 utilizes Polyphenylene Sulfide (PPS) glass-filled insulation material, providing improved thermal and chemical resistance compared to the Polyamide (PA46) Nylon 4/6 insulation in the M80-6170445.

Mechanical Compatibility: Both connectors maintain identical pitch, row spacing, mounting configuration, shrouding, and fastening mechanisms, ensuring direct mechanical interchangeability in existing PCB layouts and cable assemblies.

Contact Post Length Variation: The M80-7530445 features a contact post length of 0.177" (4.50mm) compared to 0.211" (5.35mm) in the M80-6170445. This dimensional difference requires verification against specific PCB through-hole depth and solder joint requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the M80-7530445 be used as a direct replacement for the M80-6170445 in existing designs?

A: The M80-7530445 maintains mechanical and electrical compatibility with the M80-6170445 across all critical parameters including pitch, row spacing, number of positions, mounting type, and shrouding configuration. The primary consideration is the contact post length difference (0.177" vs. 0.211"), which must be evaluated against PCB through-hole specifications and solder joint requirements for the specific application.

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

A: The primary differences are: (1) Product status—M80-7530445 is active while M80-6170445 is obsolete; (2) RoHS compliance—M80-7530445 is ROHS3 compliant while M80-6170445 is non-compliant; (3) Voltage rating—M80-7530445 provides 800V versus 120V; (4) Insulation material—M80-7530445 uses PPS glass-filled material versus Polyamide in M80-6170445; (5) Contact post length—M80-7530445 is 0.177" versus 0.211" in M80-6170445.

Q: Are there any compatibility concerns with the contact post length difference?

A: The contact post length difference of 0.034" (0.86mm) between the two connectors requires evaluation against the specific PCB design. Verify that the M80-7530445's shorter post length accommodates the target PCB through-hole depth and provides adequate solder joint formation. This is a design-specific consideration that must be confirmed for each application.

Q: Does the M80-7530445 maintain the same electrical performance?

A: Both connectors maintain equivalent current rating of 2.2A per contact and identical operating temperature range of -55°C to 125°C. The M80-7530445 provides enhanced voltage rating of 800V compared to 120V in the M80-6170445, offering greater electrical margin for applications requiring higher voltage tolerance.

Q: What is the significance of the insulation material change from Polyamide to PPS?

A: Polyphenylene Sulfide (PPS) glass-filled insulation in the M80-7530445 provides improved thermal stability, chemical resistance, and dimensional stability compared to Polyamide (PA46) Nylon 4/6 in the M80-6170445. This material upgrade supports the enhanced voltage rating and improved compliance certifications of the substitute part.

Q: Is the M80-7530445 available in equivalent quantities?

A: The M80-7530445 is currently in active production with 1058 pieces in stock, compared to 651 pieces available for the obsolete M80-6170445. The active status of the M80-7530445 ensures ongoing availability for future production requirements.
