Substitute Part Grouping Explanation

Substitute parts for trimmer capacitor 9702-0 are selected strictly based on matching key electrical and mechanical parameters: capacitance range, rated voltage, adjustment type, mounting style, size/dimension, height, operating temperature, quality factor (Q) at specified frequency, compliance with RoHS, and bulk packaging. All listed substitute models share an “Active” status and consistent compliance designations, with the only differences appearing in minor dimensional tolerances and stated features. Substitution logic excludes any parts that do not strictly match these criteria.

The key substitution parameters are:

Capacitance Range: 0.5 ~ 2.5pF
Rated Voltage: 250 V
Adjustment Type: Top
Mounting Type: Surface Mount
Size / Dimension
Height - Seated (Max)
Operating Temperature Range
Q @ Frequency
RoHS Compliance Status

Engineering Selection Recommendations

All substitute parts listed share the same product status of “Active,” identical capacitance range, rated voltage, Q at frequency, mounting style, adjustment type, packaging, Moisure Sensitivity Level (MSL), and compliance status (RoHS compliant or ROHS3 compliant). The substitute series (Thin-Trim®) and operating temperature range are also matched. Selection among 9702-0, 9402-0, 9402-0SL-1, and 9702-0SL-1 is consistent with inventory availability and compliance documentation (RoHS and REACH). Dimensional differences are within the provided parameters for this group.

Frequently Asked Questions (FAQ)

Q: What parameters must match when substituting trimmer capacitors in the Thin-Trim® series?
A: Substitute selection must strictly match capacitance range, voltage rating, adjustment type, mounting style, size/dimension, operating temperature range, quality factor at frequency, packaging, RoHS compliance status, and moisture sensitivity.

Q: Is the dimensional difference between 9702-0 and 9402-0 significant for substitution?
A: Both models share the same seated height and mounting type; diameter varies minimally (0.145" vs. 0.141”) and is within the allowable range for the category as provided.

Q: Are RoHS compliance status and packaging type required for substitution approval?
A: Yes. All substitutes must match RoHS compliance (RoHS or ROHS3 compliant) and bulk packaging status as per the provided criteria.

Q: Can substitute models be used interchangeably in surface mount applications?
A: Yes; all models are surface mount and conform to the specified profile, adjustment type, and related electrical/mechanical parameters.

Q: What is the significance of “Active” part status in selecting substitutes?
A: Only models with “Active” part status are eligible substitutes as they are in current production and supported by the manufacturer.
