Substitute Part Grouping Explanation

Substitution eligibility for the GRM1555C1H7R9DA01D is determined by the following critical parameters:

• Capacitance value: 7.9 pF (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Temperature coefficient: C0G/NP0 (required for stability)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)
• Mounting type: Surface Mount, MLCC
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1

Substitute parts are grouped into three categories based on package configuration and tolerance specifications:

MFR Recommended: GRM0335C1H7R9CA01D (0201 package, tighter tolerance ±0.25pF, active product status)

Parametric Equivalent: GJM1555C1H7R9DB01D (0402 package, same tolerance ±0.5pF, active product status, same footprint)

Direct Equivalent: 04025A7R9BAT2A (0402 package, tighter tolerance ±0.1pF, active product status, same footprint)

Parameter Comparison

Engineering Selection Recommendations

For Direct Footprint Replacement (0402 Package):

GJM1555C1H7R9DB01D and 04025A7R9BAT2A are both active products with identical 0402 package dimensions and can be used as direct substitutes without PCB layout modifications. Both maintain ROHS3 compliance and MSL 1 rating. GJM1555C1H7R9DB01D is a Murata product with the same tolerance as the main part. 04025A7R9BAT2A offers tighter tolerance (±0.1pF) from KYOCERA AVX.

For Space-Constrained Applications:

GRM0335C1H7R9CA01D provides a smaller 0201 package footprint (0.60mm x 0.30mm versus 1.00mm x 0.50mm) with improved tolerance (±0.25pF) and active product status. PCB layout redesign is required for this substitution due to package size difference.

Compliance and Availability:

All substitute parts are ROHS3 compliant and carry MSL 1 rating, matching the original part's environmental specifications. All three substitutes are active products with current manufacturing status, ensuring long-term availability compared to the Not For New Designs status of GRM1555C1H7R9DA01D.

Frequently Asked Questions (FAQ)

Q: Can GRM0335C1H7R9CA01D replace GRM1555C1H7R9DA01D without PCB modifications?

A: No. GRM0335C1H7R9CA01D uses a 0201 package (0.60mm x 0.30mm) while the main part uses 0402 (1.00mm x 0.50mm). PCB footprint redesign is required.

Q: What is the difference between GJM1555C1H7R9DB01D and 04025A7R9BAT2A?

A: Both are 0402 package equivalents with identical footprints. GJM1555C1H7R9DB01D is manufactured by Murata with ±0.5pF tolerance. 04025A7R9BAT2A is manufactured by KYOCERA AVX with tighter ±0.1pF tolerance. Electrical performance is equivalent for general purpose applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's compliance status.

Q: Why is the main part marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. All three substitute parts are active products with current manufacturing support, making them suitable for new designs and ongoing production.

Q: Does tolerance difference affect substitutability?

A: Tolerance differences (±0.5pF, ±0.25pF, ±0.1pF) do not prevent substitution as all values fall within acceptable capacitance range for the 7.9 pF specification. Tighter tolerance parts (±0.1pF, ±0.25pF) provide improved precision if required by circuit design.

Q: Can I use these parts interchangeably in production?

A: GJM1555C1H7R9DB01D and 04025A7R9BAT2A are direct footprint replacements and can be used interchangeably. GRM0335C1H7R9CA01D requires PCB layout changes due to package size difference.
