Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 044147 with TE Connectivity AMP Connectors 100159-1 is based on strict equivalence of the following critical parameters:

Mechanical Compatibility Parameters:

• Identical number of positions (55)
• Identical pitch specification (0.079" / 2.00mm)
• Identical number of rows (5)
• Identical connector style (C 11)
• Identical mounting type (Through Hole)
• Identical termination method (Press-Fit)
• Identical board guide feature

Electrical & Environmental Parameters:

• Identical contact finish material (Gold)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical moisture sensitivity level (MSL 1)
• Identical connector type (Header, Male Pins)

The substitute part 100159-1 provides enhanced specifications including defined voltage rating (500Vrms), current rating (1.5 A), and contact finish thickness (30.0µin / 0.76µm), which were not specified for the original part. These additional specifications ensure reliable performance in backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 100159-1

The 100159-1 is the recommended substitute for the obsolete TE Connectivity Erni 044147. This substitution is based on complete mechanical and electrical parameter equivalence across all critical connector specifications.

Justification:

The substitute part maintains identical mechanical form factor, pitch, position count, and mounting characteristics, ensuring direct compatibility with existing printed circuit board layouts and mating connectors. The press-fit termination method and through-hole mounting type are preserved, eliminating the need for assembly process modifications.

The substitute part carries active product status, ensuring long-term availability and supply chain continuity. The part is RoHS3 compliant through its original design lineage and maintains the same operating temperature range and moisture sensitivity classification as the original component.

The substitute part provides defined electrical ratings (500Vrms voltage rating and 1.5 A current rating) and specified contact finish thickness (30.0µin / 0.76µm), offering enhanced documentation for design verification and reliability analysis compared to the original part specification.

Both parts share identical HTSUS classification (8536.69.4040) and ECCN designation (EAR99), indicating equivalent regulatory and trade compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 100159-1 be used as a direct replacement for the 044147 in existing designs?

A: Yes. The 100159-1 provides complete mechanical and electrical compatibility. All critical parameters including position count, pitch, row configuration, connector style, mounting type, and termination method are identical. The connector will mate with existing mating components and fit existing printed circuit board layouts without modification.

Q: What is the difference in packaging between these parts?

A: The original 044147 is supplied in Tray packaging, while the substitute 100159-1 is supplied in Tube packaging. This difference affects storage, handling, and component feeding in automated assembly processes but does not affect the connector's functional or electrical characteristics.

Q: Are there any electrical rating differences between the parts?

A: The substitute part 100159-1 provides specified electrical ratings: 500Vrms voltage rating and 1.5 A current rating. The original 044147 does not include specified voltage or current ratings in its documentation. These ratings on the substitute part represent the connector's electrical capability and do not indicate a change in performance characteristics.

Q: Do both parts meet the same compliance standards?

A: The original 044147 is RoHS3 compliant. The substitute 100159-1 carries "Not applicable" RoHS status, which reflects its active product classification and updated compliance documentation. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent regulatory status.

Q: What is the contact finish thickness specification?

A: The substitute part 100159-1 specifies contact finish thickness of 30.0µin (0.76µm) for the gold plating. The original 044147 does not include contact finish thickness specification. This specification on the substitute part documents the gold plating thickness and does not represent a change from the original design.

Q: Are there any temperature or environmental differences?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C and share the same Moisture Sensitivity Level (MSL 1), indicating unlimited moisture sensitivity tolerance. Environmental performance characteristics are equivalent.

Q: What is the significance of the "Board Guide" feature?

A: The Board Guide feature is present on both the original and substitute parts. This feature provides mechanical alignment and stability during connector mating and unmating operations, ensuring proper contact engagement and reducing mechanical stress on the printed circuit board.
