Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP104PJ510CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 51 Ohm (exact match)
• Tolerance: ±5% (exact match)
• Number of resistors: 4 (exact match)
• Circuit type: Isolated (exact match)
• Power per element: 62.5mW (exact match)
• Temperature coefficient: ±200ppm/°C (exact match)
• Number of pins: 8 (exact match)

Mechanical Equivalence Requirements:

• Package / Case: 0804, Convex, Long Side Terminals (exact match)
• Mounting type: Surface Mount (exact match)
• Size / Dimension: 0.079" L x 0.039" W (2.00mm x 1.00mm) (exact match)

Environmental & Compliance Requirements:

• Operating temperature range: -55°C minimum and 155°C maximum (substitute must meet or exceed)
• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

All identified substitute parts meet these criteria and are classified as Direct or Similar equivalents based on manufacturer qualification status and application certifications.

Parameter Comparison

Engineering Selection Recommendations

RAVF104DJT51R0 (Stackpole Electronics Inc) is classified as a Direct equivalent. This part maintains identical electrical and mechanical specifications to the RP104PJ510CS. The RAVF104DJT51R0 carries Automotive AEC-Q200 qualification, indicating suitability for automotive applications. Operating temperature range extends to -55°C ~ 155°C, matching the main part specification. Height seated maximum of 0.50mm is within acceptable tolerance for 0804 package variants. ROHS3 compliance and MSL 1 rating confirm environmental compatibility.

YC124-JR-0751RL (YAGEO) is classified as a Direct equivalent. This part meets all electrical specifications and mechanical dimensions of the RP104PJ510CS. The YC124-JR-0751RL carries Automotive AEC-Q200 qualification and is specified for DDRAM and SDRAM applications. Operating temperature range is -55°C ~ 155°C. Height seated maximum of 0.55mm represents the maximum variance among substitute options but remains within 0804 package specifications. ROHS3 compliance and MSL 1 rating are confirmed.

EXB-28V510JX (Panasonic Electronic Components) is classified as a Similar equivalent. This part matches all electrical specifications and mechanical dimensions of the RP104PJ510CS. The EXB-28V510JX carries Automotive AEC-Q200 qualification. Operating temperature range is specified as -55°C ~ 125°C, which is 30°C lower than the main part maximum. Height seated maximum of 0.45mm matches the RP104PJ510CS exactly. ROHS3 compliance and MSL 1 rating are confirmed. Selection of this part requires verification that the -55°C ~ 125°C operating range is sufficient for the intended application.

All substitute parts are Active status with current manufacturing availability and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can RAVF104DJT51R0 be used as a direct replacement for RP104PJ510CS?

A: Yes. RAVF104DJT51R0 meets all electrical and mechanical specifications of RP104PJ510CS. Both parts feature 51 Ohm ±5% resistance, 62.5mW power per element, ±200ppm/°C temperature coefficient, 8-pin isolated configuration, and 0804 package with identical dimensions. Operating temperature ranges are identical (-55°C ~ 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between Direct and Similar equivalents?

A: Direct equivalents match all specified parameters including operating temperature range. Similar equivalents match electrical and mechanical specifications but may have minor variations in secondary parameters. EXB-28V510JX is classified as Similar because its operating temperature maximum is 125°C versus 155°C for the main part and Direct equivalents.

Q: Are there height differences between substitute parts?

A: Yes. Height seated maximum varies: RP104PJ510CS and EXB-28V510JX are 0.45mm, RAVF104DJT51R0 is 0.50mm, and YC124-JR-0751RL is 0.55mm. All variations remain within 0804 package specifications. Height differences may affect PCB layout clearance in space-constrained designs.

Q: Do all substitute parts support automotive applications?

A: Yes. RAVF104DJT51R0, YC124-JR-0751RL, and EXB-28V510JX all carry Automotive AEC-Q200 qualification. The RP104PJ510CS does not specify automotive qualification in the provided data.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates Moisture Sensitivity Level 1, meaning the component has unlimited shelf life and requires no special moisture control during storage or handling. All parts in this comparison carry MSL 1 rating.

Q: Can EXB-28V510JX be used in applications requiring -55°C ~ 155°C operation?

A: No. EXB-28V510JX is specified for -55°C ~ 125°C operation. Applications requiring operation above 125°C must use RP104PJ510CS, RAVF104DJT51R0, or YC124-JR-0751RL.

Q: Are all parts ROHS3 compliant?

A: Yes. RP104PJ510CS, RAVF104DJT51R0, YC124-JR-0751RL, and EXB-28V510JX are all ROHS3 compliant and REACH unaffected.
