BTEM8P-1RLF Equivalent & Substitute Parts

Part Overview

The BTEM8P-1RLF is a rectangular connector header manufactured by Amphenol ICC (FCI) in the Board Mate series. This through-hole, right-angle connector features 8 positions at 0.049" (1.25mm) pitch with shrouded 4-wall design and press-fit/solder termination. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and new production alternatives.

Substitute Part Grouping Explanation

Substitution eligibility for the BTEM8P-1RLF is determined by strict alignment of the following critical parameters:

Connector type (Header) and contact type (Male Pin)
Mating pitch (0.049" / 1.25mm)
Position count (8) and row configuration (1 row)
Mounting method (Through Hole, Right Angle)
Shrouding design (Shrouded - 4 Wall)
Board-to-cable/wire connection style
Contact shape (Square)
Flammability compliance (UL94 V-0)

The substitute part 1734829-8 from TE Connectivity AMP Connectors meets all these core electrical and mechanical compatibility criteria. While minor variations exist in contact material, insulation composition, and dimensional specifications, these differences remain within acceptable tolerance for functional equivalence in the rectangular connector category.

Engineering Selection Recommendations

The 1734829-8 serves as a direct functional substitute for the obsolete BTEM8P-1RLF. Both connectors share identical mating pitch, position count, mounting configuration, and shrouding design. The substitute part carries Last Time Buy status, indicating continued manufacturer support with defined end-of-life parameters, whereas the main part is fully obsolete.

Both parts maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental performance. The substitute part includes specified operating temperature range (-25°C ~ 85°C), current rating (1A), and voltage rating (125V), providing defined electrical performance parameters.

Contact material differs between the parts (brass versus phosphor bronze) and insulation composition varies (PBT versus PA9T nylon), with corresponding dimensional variations in post length and insulation height. These material and dimensional differences remain within acceptable substitution tolerance for rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 1734829-8 directly replace the BTEM8P-1RLF in existing designs?

A: Yes. Both connectors share identical mating pitch (0.049" / 1.25mm), position count (8), row configuration (1), mounting type (through-hole right-angle), and shrouding design (4-wall). The core mechanical and electrical interface parameters are equivalent.

Q: What are the dimensional differences between these parts?

A: The substitute part (1734829-8) has a shorter contact post length (0.091" versus 0.118") and lower insulation height (0.126" versus 0.177"). These dimensional variations must be evaluated against specific PCB layout and mating component requirements in your application.

Q: Why do the contact materials differ?

A: The main part uses brass contacts while the substitute uses phosphor bronze. Both materials are tin-finished and suitable for the specified electrical parameters. Material selection reflects different manufacturing approaches between Amphenol ICC and TE Connectivity.

Q: Are there compliance or certification differences?

A: Both parts carry UL94 V-0 flammability rating and MSL 1 (unlimited moisture sensitivity). The substitute part specifies RoHS3 compliance. Both share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the inventory status for each part?

A: The BTEM8P-1RLF has 905 pieces in stock but is obsolete with no future availability. The 1734829-8 has 9542 pieces available and carries Last Time Buy status, providing a defined procurement window before discontinuation.

Q: Should I consider the operating temperature specification?

A: The substitute part specifies -25°C ~ 85°C operating range with 1A current and 125V voltage ratings. The main part does not provide these electrical specifications. Verify these parameters align with your application requirements.
