TE Connectivity 104549-8 Rectangular Connector Header SMD 60 Position 1.27mm Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104549-8 is a surface mount rectangular connector header from the AMPMODU System 50 series. This component is a shrouded, 60-position male pin header with 1.27mm pitch designed for board-to-board or cable applications. The part is classified as Active product status and is suitable for automotive, general purpose, medical, and telecommunications applications. Identifying equivalent and substitute parts is necessary when bulk packaging is unavailable, when alternative packaging formats are required, or when inventory constraints necessitate sourcing from alternative stock configurations.

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The substitute part 5-104549-8 is functionally equivalent to the main part 104549-8 based on the following critical parameters:

Electrical Equivalence Criteria:

• Identical connector type (Header)
• Identical contact type (Male Pin)
• Identical number of positions (60)
• Identical number of rows (2)
• Identical pitch - mating (0.050" / 1.27mm)
• Identical row spacing - mating (0.100" / 2.54mm)
• Identical voltage rating (30VAC)
• Identical operating temperature range (-65°C ~ 105°C)

Mechanical Equivalence Criteria:

• Identical mounting type (Surface Mount)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical termination method (Solder)
• Identical insulation material (Polyphthalamide / PPA)
• Identical insulation height (0.435" / 11.05mm)
• Identical contact shape (Circular)
• Identical contact length - mating (0.125" / 3.18mm)
• Identical fastening type (Latch Holder)
• Identical material flammability rating (UL94 V-0)

Packaging Difference: The substitute part differs only in packaging format: bulk packaging (104549-8) versus tube packaging (5-104549-8). This packaging distinction does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 104549-8 and 5-104549-8 are Active product status components from TE Connectivity AMP Connectors within the AMPMODU System 50 series. The parts are electrically and mechanically equivalent across all critical parameters including connector type, contact configuration, pitch, mounting method, and operating specifications.

The primary distinction between these parts is packaging format and regulatory compliance status. The 5-104549-8 substitute part is ROHS3 compliant, whereas the main part 104549-8 carries a "Not applicable" RoHS status. For applications requiring RoHS3 compliance, the 5-104549-8 is the appropriate selection. For applications without RoHS compliance requirements, either part is suitable based on packaging availability.

The contact finish post specification differs between the two parts: the main part specifies Tin-Lead while the substitute specifies Tin. Both finishes are functionally equivalent for solder termination applications and do not affect electrical performance or mechanical compatibility.

Selection between these parts should be based on packaging requirements and regulatory compliance mandates specific to the end application and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Are the 104549-8 and 5-104549-8 electrically interchangeable?

A: Yes. Both parts are electrically equivalent. They share identical electrical specifications including 60-position configuration, 1.27mm pitch, 30VAC voltage rating, and -65°C to 105°C operating temperature range.

Q: What is the difference between these two parts?

A: The primary differences are packaging format (bulk versus tube) and RoHS compliance status. The 5-104549-8 is ROHS3 compliant while the 104549-8 is not applicable for RoHS. The contact finish post differs slightly (Tin-Lead versus Tin), but both are functionally equivalent for solder termination.

Q: Can I use the 5-104549-8 as a direct replacement for the 104549-8?

A: Yes, the 5-104549-8 is a direct functional equivalent. The parts are mechanically and electrically identical. Selection depends on packaging requirements and whether RoHS3 compliance is mandated for your application.

Q: Does the packaging difference affect component performance?

A: No. Packaging format (bulk versus tube) does not affect electrical or mechanical performance. The choice between packaging types is determined by supply chain logistics, inventory management, and handling requirements.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts have identical surface mount specifications, solder termination requirements, and mechanical footprints. They are fully compatible with standard PCB assembly processes.

Q: Which part should I specify for new designs?

A: For new designs, specify the 5-104549-8 if RoHS3 compliance is required or preferred. Both parts are Active status and suitable for automotive, general purpose, medical, and telecommunications applications. Verify packaging availability based on your procurement volume requirements.

Q: Is the Tin-Lead versus Tin contact finish difference significant?

A: No. Both contact finishes are functionally equivalent for solder termination applications. The difference does not affect electrical performance, mechanical compatibility, or reliability in the specified operating temperature range.
