Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary substitute identified for TE Connectivity 499376-9 is part number 5499376-9, which maintains identical specifications across all critical dimensions and electrical ratings.

The substitution logic is based on the following key parameters:

• Connector Configuration: 40-position, 2-row header with 0.100" (2.54mm) pitch and row spacing
• Mounting Specification: Through-hole, right-angle orientation with shrouded 4-wall construction
• Electrical Performance: 1A per contact at 250VAC operating range
• Thermal Compatibility: -65°C ~ 105°C operating temperature range
• Contact Geometry: Male pin contacts with square shape, 0.240" (6.10mm) mating length and 0.155" (3.94mm) post length
• Termination Method: Solder termination with tin-lead or tin post finish
• Fastening Mechanism: Latch lock/eject hooks with short configuration
• Flammability Compliance: UL94 V-0 material rating

Parts meeting all these parameters are classified as direct equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5499376-9 is electrically and mechanically equivalent to the main part 499376-9 across all specified parameters. Both parts are active products from TE Connectivity AMP Connectors and maintain identical connector configuration, contact specifications, and electrical ratings.

A key distinction exists in regulatory compliance status. The main part 499376-9 is RoHS non-compliant, while the substitute part 5499376-9 is ROHS3 compliant. This difference is significant for applications subject to RoHS directives and should be evaluated against project requirements.

Both parts carry identical REACH Affected status and EAR99 export classification. The contact finish on the post differs slightly: the main part specifies tin-lead, while the substitute specifies tin. This difference reflects modern lead-free manufacturing practices and does not affect electrical or mechanical compatibility.

Selection between these parts should be based on regulatory compliance requirements and inventory availability. The ROHS3-compliant substitute part 5499376-9 is suitable for applications requiring lead-free components and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can 5499376-9 be used as a direct replacement for 499376-9?
