Equivalent & Substitute Parts for 78286-422HLF

Part Overview

The Amphenol ICC 78286-422HLF is a rectangular connector header classified as BERGSTIK® II series, featuring a vertical through-hole mount configuration with 22 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is designed for board-to-board applications with unshrouded, push-pull fastening and solder termination. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78286-422HLF is determined by strict alignment of the following critical parameters:

• Connector Configuration: 22 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Mounting and Termination: Through-hole solder termination with push-pull fastening
• Electrical Interface: Male pin contact type for board-to-board connectivity
• Physical Characteristics: Unshrouded header design with UL94 V-0 flammability rating
• Environmental Classification: MSL 1 (Unlimited) moisture sensitivity

The two substitute parts identified—TE Connectivity 1-87215-3 and 6-146252-1—both satisfy these core substitution criteria. Both are active-status AMPMODU Mod II series connectors with identical position counts, pitch specifications, and mounting configurations. Variations in contact geometry, finish specifications, and insulation materials represent secondary design differences that do not preclude functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitutes are active-status components with current manufacturing support, addressing the obsolescence of the original Amphenol ICC part. Selection between the two alternatives depends on specific application requirements:

1-87215-3 is suitable for applications where circular contact geometry and thermoplastic insulation material are acceptable. This part carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements for new designs.

6-146252-1 provides breakaway connector capability in addition to standard header functionality, with liquid crystal polymer insulation offering enhanced thermal and chemical resistance. This part carries RoHS compliance certification and is recommended where mechanical robustness and material performance are prioritized.

Both parts maintain the critical electrical and mechanical parameters of the original 78286-422HLF: 22-position, 2-row configuration at 0.100" pitch with through-hole solder termination and push-pull fastening. Both achieve UL94 V-0 flammability rating and MSL 1 classification. The contact finish upgrade from tin to gold in both substitutes provides improved corrosion resistance and contact reliability compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can 1-87215-3 and 6-146252-1 be used interchangeably with 78286-422HLF?

A: Both parts satisfy the core substitution criteria: identical position count (22), row configuration (2 rows), pitch (0.100"), mounting type (through-hole), termination (solder), and fastening (push-pull). Mechanical and electrical compatibility is established. Secondary differences in contact shape, finish, and insulation material do not affect functional substitution within the defined parameter set.

Q: What is the significance of the breakaway feature in 6-146252-1?

A: The breakaway feature allows individual connector sections to be separated after assembly. This provides design flexibility for applications requiring modular connector configurations. The feature does not affect compatibility with standard mating interfaces designed for the original 78286-422HLF.

Q: How do the contact finish differences affect performance?

A: The original 78286-422HLF uses tin plating (100.0µin thickness). Both substitutes use gold plating with lower thickness specifications (30.0µin for 1-87215-3, 15.0µin for 6-146252-1). Gold provides superior corrosion resistance and contact reliability, particularly in environments with moisture or corrosive atmospheres. This represents a performance improvement over the original part.

Q: Are there compliance differences between the two substitutes?

A: 1-87215-3 carries ROHS3 Compliant and REACH Affected designations. 6-146252-1 carries RoHS Compliant designation. Both meet UL94 V-0 flammability requirements. Selection should align with specific regulatory requirements of the target application and market.

Q: What is the impact of insulation material differences?

A: The original part does not specify insulation material. 1-87215-3 uses thermoplastic insulation; 6-146252-1 uses liquid crystal polymer (LCP). LCP offers superior thermal stability and chemical resistance, making it suitable for demanding environmental conditions. Thermoplastic provides adequate performance for standard industrial applications.

Q: Do the substitutes support the same current and voltage ratings?

A: Both substitutes specify 3A current rating. The original part does not provide current or voltage specifications. Both substitutes are rated for -65°C to 105°C operating temperature range, exceeding typical industrial requirements.
