SPS-01T-187 Equivalent & Substitute Parts

Part Overview

The SPS-01T-187 is a 0.187" (4.75mm) Quick Connect Female crimp connector manufactured by JST Sales America Inc., designed for wire gauges 20-26 AWG in non-insulated applications. This terminal operates as a free-hanging in-line connector with brass contacts finished in tin. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this connector category, enabling component interchangeability in applications where the primary part is unavailable or when alternative packaging formats are preferred.

Key Parameters

Parameter	Value
Tab Width	0.187" (4.75mm)
Tab Thickness	0.020" (0.51mm)
Wire Gauge Range	20-26 AWG
Termination Type	Crimp
Gender	Female
Contact Material	Brass with Tin Finish
Insulation Type	Non-Insulated
Mounting Type	Free Hanging (In-Line)
RoHS Status	Compliant
MSL Rating	1 (Unlimited)

Substitute Part Grouping Explanation

Substitution eligibility for the SPS-01T-187 is determined by strict alignment of the following critical parameters:

Tab width and thickness (0.187" × 0.020") for mechanical fit compatibility
Wire gauge range overlap (minimum 20 AWG support required)
Crimp termination method
Female gender configuration
Brass contact material with tin finish
Non-insulated construction
Free-hanging in-line mounting
RoHS compliance status
MSL 1 rating

The substitute part 63196-1 qualifies based on these criteria. While the wire gauge range differs (20-24 AWG versus 20-26 AWG), the overlap at 20-24 AWG ensures compatibility for applications within this shared range. Tab length and overall length variations are acceptable as they do not affect electrical or mechanical interchangeability within the quick-connect interface specification.

Engineering Selection Recommendations

Both the SPS-01T-187 and 63196-1 are active production parts with full RoHS compliance and MSL 1 ratings, making them suitable for equivalent applications. Selection between these parts should be based on:

Wire gauge requirements: Use SPS-01T-187 for applications requiring 25-26 AWG support; use 63196-1 for applications within the 20-24 AWG range
Insulation diameter compatibility: Verify that wire insulation diameter falls within the acceptable range for the selected part (0.060" ~ 0.110" overlap region is safe for both)
Packaging format: SPS-01T-187 is supplied in Tape & Reel format; 63196-1 is supplied in Cut Tape format
Inventory availability: SPS-01T-187 has 671 units in stock; 63196-1 has 19,882 units in stock

Both parts meet the same electrical and mechanical specifications within their respective wire gauge ranges and are suitable for direct substitution in applications where wire gauge requirements align.

Frequently Asked Questions (FAQ)

Q: Can 63196-1 replace SPS-01T-187 in all applications?

A: 63196-1 can replace SPS-01T-187 only in applications using wire gauges 20-24 AWG. Applications requiring 25-26 AWG wire support must use SPS-01T-187, as 63196-1 does not support these gauges.

Q: What is the significance of the tab width and thickness specifications?

A: Tab width (0.187") and thickness (0.020") define the mechanical interface with the mating connector. Both parts share identical specifications, ensuring physical compatibility with the same quick-connect receptacle.

Q: Are there differences in insulation diameter compatibility?

A: Yes. SPS-01T-187 accepts insulation diameters from 0.051" to 0.134", while 63196-1 accepts 0.060" to 0.110". The overlapping range (0.060" to 0.110") is compatible with both parts. Wires with insulation below 0.060" or above 0.110" may only be compatible with one part.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats do not affect electrical or mechanical performance. The difference is in handling and storage logistics only.

Q: Are both parts RoHS compliant?

A: Yes. Both SPS-01T-187 and 63196-1 are RoHS compliant with MSL 1 (unlimited moisture sensitivity) ratings, meeting the same environmental and regulatory standards.

Q: What is the difference in tab length between these parts?

A: SPS-01T-187 has a tab length of 0.252" (6.40mm), while 63196-1 has 0.270" (6.86mm). This variation does not affect interchangeability, as both lengths function within the quick-connect interface specification.
