Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-1814655-7 is determined by the following critical parameters:

Mechanical Compatibility:

• Number of positions: 5 (1 x 5) configuration
• Pitch spacing: 0.100" (2.54mm) for both mating and post
• Mounting type: Through hole
• Housing material compatibility with PCB assembly processes

Electrical Compatibility:

• Operating temperature range: Substitute must support minimum -55°C to 105°C or higher
• Contact resistance: Substitute contact resistance must be specified and suitable for signal integrity
• Contact material and finish: Determines signal quality and environmental resistance

Manufacturing and Compliance:

• RoHS compliance status
• Moisture sensitivity level (MSL): 1 (Unlimited)
• Material flammability rating: UL94 V-0

The Aries Electronics 05-0501-20 qualifies as a substitute based on matching mechanical pitch, position count, through-hole mounting, and compliance certifications. Differences in contact finish material, termination method, and operating temperature maximum are documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 4-1814655-7 is obsolete, while the Aries Electronics 05-0501-20 is active and currently manufactured. For new designs or ongoing production support, the active substitute part ensures continued availability and supply chain stability.

Compliance and Certification: Both parts meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings. The Aries Electronics substitute meets ROHS3 compliance, which represents the current regulatory standard. Both parts carry EAR99 ECCN classification and identical HTSUS codes, indicating equivalent regulatory treatment.

Operating Temperature: The original TE Connectivity part operates to 125°C maximum, while the Aries Electronics substitute operates to 105°C maximum. Applications requiring operation above 105°C cannot use the substitute without thermal performance verification.

Termination Method Difference: The original part uses solder termination, while the substitute uses wire wrap termination. PCB design and assembly processes must accommodate the wire wrap post length of 0.420" (10.67mm) compared to the original 0.114" (2.90mm) solder post length. This difference requires PCB layout modification.

Contact Finish and Material: The original part features gold-plated beryllium copper mating contacts. The substitute features tin-plated phosphor bronze mating contacts. Gold plating provides superior corrosion resistance and lower contact resistance in low-signal-level applications. Tin plating is suitable for standard signal applications but may exhibit higher contact resistance over extended environmental exposure.

Frequently Asked Questions (FAQ)

Q: Can the Aries Electronics 05-0501-20 be used as a direct replacement for the TE Connectivity 4-1814655-7 in existing PCB designs?

A: Direct PCB replacement is not possible without design modification. The substitute part uses wire wrap termination with a 0.420" post length, while the original uses solder termination with a 0.114" post length. PCB footprints and via placement must be redesigned to accommodate the longer wire wrap posts.

Q: What is the impact of the different contact finish materials on signal integrity?

A: The original part's gold-plated beryllium copper contacts provide lower contact resistance (specified at 10mOhm) and superior corrosion resistance. The substitute's tin-plated phosphor bronze contacts are suitable for standard signal applications. Contact resistance for the substitute is not specified in available documentation. For high-reliability or low-signal-level applications, the original contact finish is preferred.

Q: Does the 20°C difference in maximum operating temperature affect substitution suitability?

A: The substitute's maximum operating temperature of 105°C is 20°C lower than the original's 125°C rating. Applications operating continuously above 105°C require the original part or alternative substitutes with higher temperature ratings. Applications with maximum operating temperatures at or below 105°C are compatible with the substitute.

Q: Are both parts RoHS compliant?

A: Yes. The original TE Connectivity part is RoHS Compliant. The Aries Electronics substitute is ROHS3 Compliant, which represents the current RoHS standard. Both parts meet regulatory requirements for RoHS-restricted substance limitations.

Q: What is the inventory status of these parts?

A: The TE Connectivity 4-1814655-7 has 764 pieces in stock as new original inventory. The Aries Electronics 05-0501-20 has 965 pieces in stock as new original inventory in bulk packaging. Both parts are available for immediate procurement.

Q: How do the termination methods affect assembly and rework processes?

A: Solder termination (original part) integrates with standard PCB wave soldering and reflow processes. Wire wrap termination (substitute part) requires wire wrap tooling and manual or automated wire wrap assembly equipment. Rework and repair processes differ significantly between the two termination methods.
