Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 4-176264-8 and the equivalent part 4-5176264-8 is based on identical electrical and mechanical parameters across all critical dimensions and performance specifications. Both connectors share the same AMPMODU series designation, identical contact configuration (50 positions, 2 rows), matching pitch specifications (0.079" mating pitch and row spacing), and equivalent operating characteristics (temperature range -40°C to 105°C, 200VAC voltage rating).

The substitution is valid based on the following key parameters:

• Connector type, contact type, and breakaway configuration
• Position count and row configuration
• Mating pitch and row spacing dimensions
• Contact length specifications (mating, post, and overall)
• Insulation height and contact shape
• Mating contact finish (gold) and thickness
• Operating temperature range
• Voltage rating and flammability rating
• Through-hole solder termination method
• Push-pull fastening type

The primary distinction between these parts relates to product status (obsolete versus active), packaging format, post contact finish composition (tin-lead versus tin), and regulatory compliance status (RoHS non-compliant versus RoHS compliant).

Parameter Comparison

Engineering Selection Recommendations

The 4-5176264-8 is the direct functional equivalent for the obsolete 4-176264-8 connector header. Selection of the substitute part is appropriate for new designs and ongoing production requirements due to its active product status and improved regulatory compliance profile.

The substitute part 4-5176264-8 maintains complete electrical and mechanical compatibility with the original part across all critical parameters: identical 50-position, 2-row configuration; matching 2.00mm pitch specifications; equivalent contact dimensions and materials; and identical operating temperature and voltage ratings.

The primary advantages of the substitute part include:

• Active product status with assured long-term availability
• RoHS compliance, eliminating lead-based solder concerns in post contact finishes
• REACH unaffected status, reducing regulatory documentation requirements
• Tray packaging format suitable for automated assembly processes

The post contact finish difference (tin-lead versus tin) reflects the RoHS compliance transition. Both finishes provide equivalent solder joint reliability and electrical performance in through-hole applications. The gold-plated mating contacts remain identical, ensuring consistent contact resistance and signal integrity.

Frequently Asked Questions (FAQ)

Q: Are the 4-176264-8 and 4-5176264-8 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 50-position, 2-row configuration, 2.00mm mating pitch, row spacing, contact lengths, and insulation height. They mount identically in through-hole applications and accept the same mating connectors.

Q: What is the difference between the tin-lead and tin post finishes?

A: The 4-176264-8 features tin-lead post finish, while the 4-5176264-8 features tin post finish. This difference reflects RoHS compliance requirements. Both finishes provide equivalent electrical performance and solder joint reliability in through-hole termination applications.

Q: Can the 4-5176264-8 be used as a direct replacement in existing designs?

A: Yes. The 4-5176264-8 provides complete functional equivalence for the obsolete 4-176264-8. All electrical and mechanical parameters are identical, and the connector operates within the same temperature range (-40°C to 105°C) and voltage rating (200VAC).

Q: What is the significance of the RoHS compliance difference?

A: The 4-5176264-8 is RoHS compliant, meeting European Union restrictions on hazardous substances. The 4-176264-8 is RoHS non-compliant due to its tin-lead post finish. For applications subject to RoHS regulations or requiring lead-free components, the 4-5176264-8 is the appropriate selection.

Q: Does the packaging format affect connector performance?

A: No. The packaging format (tray for the 4-5176264-8) does not affect electrical or mechanical performance. Packaging differences relate to handling, storage, and automated assembly compatibility. The tray format is standard for production environments.

Q: Are both connectors rated for the same operating temperature range?

A: Yes. Both the 4-176264-8 and 4-5176264-8 operate across the identical temperature range of -40°C to 105°C with UL94 V-0 flammability rating.

Q: What is the contact material composition?

A: Both connectors feature brass contact material with gold-plated mating surfaces (30.0µin thickness) and tin or tin-lead plated posts, depending on the specific part number.
