Substitute Part Grouping Explanation

Substitute parts for the 776524-4 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Connector Type: Plug
Contact Type: Female Socket
Number of Positions: 4
Pitch: 0.177" (4.50mm)
Number of Rows: 2
Row Spacing: 0.209" (5.30mm)
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Fastening Type: Latch Lock
Insulation Material: Thermoplastic, Glass Filled
Operating Temperature Range: -40°C ~ 125°C
Series: AMPSEAL 16

The substitute parts 776487-1 and 776487-3 meet all of these criteria and are therefore electrically and mechanically interchangeable with the 776524-4 within the same application context.

Engineering Selection Recommendations

All three parts—776524-4, 776487-1, and 776487-3—are active products from TE Connectivity Deutsch Connectors with identical electrical and mechanical specifications. Each part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental performance characteristics.

Selection between these parts should be based on availability and supply chain requirements. The substitute parts 776487-1 and 776487-3 currently maintain higher inventory levels (1101 and 1291 units respectively) compared to the main part 776524-4 (846 units), providing alternative sourcing options for production planning and procurement strategies.

All three parts are suitable for applications requiring 4-position rectangular connectors with crimp termination in the AMPSEAL 16 series operating within the -40°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 776487-1 and 776487-3 electrically compatible with 776524-4?

A: Yes. Both substitute parts share identical electrical specifications including connector type (plug), contact type (female socket), number of positions (4), pitch (0.177"/4.50mm), and operating temperature range (-40°C to 125°C). They are electrically interchangeable.

Q: Are the substitute parts mechanically compatible with 776524-4?

A: Yes. Both substitute parts have identical mechanical specifications including dual-row configuration, row spacing (0.209"/5.30mm), mounting type (free hanging in-line), fastening type (latch lock), and insulation material (thermoplastic, glass filled). They are mechanically interchangeable.

Q: What is the difference between 776487-1 and 776487-3?

A: Both parts are parametrically equivalent to 776524-4 and to each other. The only difference is the base product number (776487 versus 776524), which reflects different manufacturing or product line designations. All electrical and mechanical parameters are identical.

Q: Can I use these parts interchangeably in my assembly?

A: Yes. The 776524-4, 776487-1, and 776487-3 are fully interchangeable within applications requiring 4-position AMPSEAL 16 series rectangular connector plugs with the specified parameters.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry identical environmental certifications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these connectors include contacts?

A: No. All three parts are connector housings only. Contacts are not included and must be sourced separately.
